Outcome data: Four main outcomes will be examined: Retention in treatment, self-reported opioid craving, self-reported drug use with urine toxicology confirmation. Retention in treatment (1-180 days) will be measured by the date that participant was last seen by study personnel or date when participant completes study following the date of enrollment. Opioid carving (1-10) will be measured by a 10 point visual analog scale. Self-reported drug use (days to first use and percent days abstinent) will be measured by time line follow back. Urine toxicology (yes/no) will be determined at baseline and monthly at 1, 2, 3, 4, 5, 6 months follow-up.
